This directory preserves both resolved investigations and approved validation gaps. Resolved files remain historical evidence; they are not current failures.

Issue	Status	Current conclusion
TC010 48-bit statfs	RESOLVED	A qualified 16 TiB-plus sparse provider completed mount and 64-bit `statfs` validation.
TC060 pathconf	RESOLVED	FreeBSD-standard values were implemented and dynamically revalidated.
TC153 large directory index	RESOLVED	The exact fixed KLD returned `EINTEGRITY` on the multi-TiB sparse-provider path.
`erofs_vget()` after `insmntque()` failure	FIXED / RUNTIME VALIDATION PENDING	The post-failure vnode access was removed; a dedicated unmount-race test remains outstanding.
Explicit mapped extent payload	SHELVED	TC146 remains PARTIAL because no independently validated positive mapped-payload fixture is available.

The remaining open validation work is split between a dedicated vnode teardown race test for the fixed lifecycle issue and a shelved fixture/tooling gap for the explicit mapped extent payload case.
